Hmm a bit weird if the upgrade only support Carplay for Mazda Malaysia. Whereas in other countries, their 2019 CX-5 are all advertised to have both Carplay and AA capabilities. I guess to know for sure, maybe someone here who has installed this can try hook up their Android phones to test it out..

(EDIT) Further checking based on my receipt above for the components serial number,
1. AUX Unit: TK78-66-9U0C
2. USB: C924-V6-605
It matches with the CP/AA installation guide:
Australia/NZ, Southern Hemisphere, South Asia, Oceania, known as '4A N' on your Touch-screen.
FIRMWARE version for '4A N' or 'ADR' for CP/AA of two .up files.cmu150_ADR_70.00.021A_failsafe.up file MUST be Installed FIRST.
cmu150_ADR_70.00.021A_reinstall.up file MUST be Installed SECOND.
C924-V6-605 New USB Data Cable set of two, MUST be Installed THIRD.
TK78-66-9U0C New AUX Unit, MUST be Installed LAST.
Only thing that I have yet to confirm is which Firmware will the SC install. If the same as above means that the upgrade will support AA functionality as well. I have gut feeling that it will, though the SC rep I met earlier could not confirm about this. So, finger-crossed...
